Definitions
- the present invention relates to the field of non-aqueous dispersion (NAD) resin based paint compositions (NAD paint compositions) that exhibit excellent mechanical and antifouling properties.
- NAD non-aqueous dispersion
- NAD paint compositions that exhibit excellent mechanical and antifouling properties.
- Non-aqueous dispersion (NAD) resin based paint compositions are known in the art, i.a. from JP 11-43629-A, JP 2000-63709-A, JP 2001-279190-A, JP 2002-194268-A and US 5,374,665.
- JP 11-43629-A discloses NAD paint compositions comprising a monobasic acid compound which contains a carboxy group, and an antifouling agent comprising a metal.
- monobasic acids include abietic acid. None of the examples describe the use of abietic acid, neither is any particular preference for abietic acid expressed.
- JP 2000-63709-A discloses NAD paint compositions comprising metal soaps of monobasic acids and an antifouling agent comprising a metal. The metal soaps are of copper, zinc, cobalt, manganese, calcium, iron, aluminium, magnesium, nickel, etc.
- abietic acid None of the examples describe the use of abietic acid, neither is any particular preference for abietic acid expressed.
- NAD paint compositions comprising an antifouling agent. Rosin is mentioned as a possible further resin that should be compatible with the NAD resin. Examples 3 and 4 illustrate NAD paint compositions comprising rosin.
- NAD resin based paint compositions In the maturing field of NAD resin based paint compositions it is an aim to prepare compositions which will result in mechanically more durable coatings as certain mechanical defects in relation to hardness after application and disintegration when exposed to weathering can be identified for the coatings of the known NAD paint compositions.
- JP 2001-279190-A addresses this problem and discloses NAD paint compositions comprising polymers of silyl esters of acrylic acids in the core and/or in the shell component of the NAD particles.
- the silyl esters constitute 5-80% by weight of the polymers.
- optional components are, e.g., mentioned pigments, fibrous materials, plasticizers, modifying resins such as soluble acrylic resins and polyvinyl ether, rosin and derivatives and metal salts thereof, hydrating agents, etc. None of the examples describe the use of rosin.
- JP 2002-194268-A discloses paint compositions, possibly NAD paint compositions having polymers of fairly complex silyl esters of acrylic acid in the core and/or in the shell component of the NAD particles.
- rosin As optional components are, e.g., mentioned pigments, rosin and derivatives and metal salts thereof, modifying resins such as acrylic resins and polyvinyl ether, plasticizers, fibrous materials, etc. None of the examples describe the use of rosin In the field of paint technology, it is generally understood that the presence of rosin in a composition will provide some beneficial properties but at the same time the mechanical properties are at stake (see, e.g., EP 0 802 243 A2).
- the present invention provides an intriguing solution to the mechanical problems realised for the known compositions by providing the antifouling paint composition defined in claim 1. This solution is uniquely surprising in that addition of rosin principles to a paint composition, albeit providing certain beneficial properties, would be expected to decrease the mechanical strength of said paint.
- the present invention thus provides an antifouling paint composition comprising a non- aqueous dispersion resin, said resin having a core-shell structure which is constituted of
- a hydrophilic core component comprising a polymer of ethylenically unsaturated monomers, 5-75% by weight of said monomers comprising free acid groups and at the most 3% by weight of said monomers comprising silyl ester groups
- a shell component comprising a polymer of ethylenically unsaturated monomers, wherein less than 3% by weight of said monomers comprising free acid groups or silyl ester groups, said resin having an acid value of in the range of 15-400 mg KOH/g wherein the core component accounts for at least 80% of the acid value of the resin
- said paint composition further comprising rosin wherein at the most 90% by weight of the rosin has conjugated, non-aromatic double bonds, at least 25% of said rosin being in the form of a metal resinate, said metal resinate constituting in the range of 1-40% by wet weight of the composition, dry weight ratio between (i) NAD and (n) rosin and metal resinates being in the range of 100' 15 to 15: 100.
- non-aqueous dispersion resin non-aqueous dispersion resin
- NAD non-aqueous dispersion resin
- shell component a resin obtained by stably dispersing a high- pola ⁇ ty, high-molecular weight resin particulate component (the “core component”) into a non-aqueous liquid medium in a low-polarity solvent using a high-molecular weight component (the “shell component”).
- the non-aqueous dispersion resin may be prepared by a method wherein a polyme ⁇ sable ethylenically unsaturated monomer which is soluble in a hydrocarbon solvent and which is polyme ⁇ sable to form a polymer (the core component) which is insoluble in the hydrocarbon solvent, is subjected to dispersion polymerisation in accordance with a conventional method in the hydrocarbon solvent in the presence of a shell component (the dispersion stabiliser) made of a polymer which dissolves or swells in the solvent.
- a shell component the dispersion stabiliser
- the non-aqueous dispersion-type resin utilised in this invention can be a resin known per se; or it can be produced like the known resins.
- Such non-aqueous dispersion-type resins and method for their preparation are described in, e.g., US 3,607,821, US 4,147,688, US 4,493,914 and US 4,960,828, Japanese Patent Publication No. 29,551/1973 and Japanese Laid-open Patent Application No. 177,068/1982.
- the shell component constituting the non-aqueous dispersion-type resin various high-molecular substances soluble in a low-polarity solvent which are described in, e.g., US 4,960,828 (Japanese Laid-open Patent Application No. 43374/1989), can be used.
- shell components such as an acrylic resin or a vinyl resin may be used.
- a copolymer of an ethylenically unsaturated monomer having a high polarity is generally applicable.
- the non-aqueous dispersion-type resin can be formed by a method known per se. Examples thereof are a method in which the core component and the shell component are previously formed by block co-polymerization or graft co-polymerization, and they are then mixed in a low-polarity solvent and, if required, reacted to form a non-aqueous dispersion (see Japanese Patent Publication No.
- the dispersion stabiliser containing in a molecule the component soluble in the low-polarity solvent and the component having affinity for the resin being dispersed, or the dispersion stabiliser of the specific composition that dissolves in the low-polarity solvent is present as the shell component, and component being dispersed as the core component is formed by copolyme ⁇ sation of the monomers.
- the core component has free acid groups or free acid groups and silyl ester groups that are convertible into the acid group by hydrolysis in sea water.
- 5-75% by weight, e.g. 5-60% by weight or 7-50% by weight, of the monomers of the core polymer should carry free acid groups.
- the free acid groups will have direct influence on the properties of the paint formulation, whereas the silyl ester groups will only have influence after hydrolysis in seawater, it is important that no more than 3% by weight of the monomers of the core component are silyl ester monomers.
- no more than 1% by weight of monomers of the core component are silyl ester monomers, and most often no silyl ester groups are present in the core.
- silyl ester monomers examples include silyl esters of acrylic or methacrylic acid.
- a smaller proportion of the free acid groups or silyl ester groups may also be contained in the shell component. It is, however, believed that less than 3% by weight of the monomers of shell component are free acid groups or silyl ester groups.
- free acid group is intended to cover the acid group in the acid form. It should be understood that such acid groups temporarily may exist on salt form if a suitable counter ion is present in the composition or in the environment. As an illustrative example, it is envisaged that some free acid groups may be present in the sodium salt form if such groups are exposed to salt water.
- the non-aqueous dispersion-type resin have a resin acid value of usually 15-400 mg KOH/g, preferably 15 to 300 mg KOH/g, such as 18 to 300 mg KOH/g. If the total acid value of the NAD resin is below 15 mg KOH/g, the polishing rate of the paint film is too low and the antifouling property will often be unsatisfactory. On the other hand, if the total acid value is above 400 mg KOH/g, the polishing rate is too high for that reason a problem of water resistance (durability of the paint coat in seawater) becomes a problem. (When the core component and/or the shell component contains the acid precursor group, the resin acid value is one given after the group is converted into the acid group by hydrolysis).
- the "resin acid value” here referred to is an amount (mg) of KOH consumed to neutralise 1 g of a resin (solids content), expressing a content of an acid group (in case of the acid precursor group, a content of an acid group formed by hydrolysis) of the resin (solids content).
- the acid group and/or the acid precursor group is contained in the core component such that the content thereof is, as a resin acid value, at least 80%, preferably at least 90%, more preferably at least 95% of the total resin acid value of the non- aqueous dispersion-type resin.
- the acid value in the core component of the NAD resin is below 80% of the total acid value of the NAD resin, i.e. the acid value of the shell component is above 20% of the total acid value
- potential problems may be as described above with respect to water resistance and durability.
- the paint composition comprises free metal ions, a problem with respect to gelation may occur if the acid value of the shell component is above 20% of the total acid value. This being said, it is normally preferred that the shell component is hydrophobic.
- the dry weight ratio of the core component to the shell component in the NAD resin is not especially limited, but is normally in the range of 90/10 to 10/90, preferably 80/20 to 25/75, such as 60/40 to 25/75.
- the dry matter of the non-aqueous dispersion resin normally constitutes in the range of 2-30%, such as 4-25%, preferably 5-25% such as 5- 20% by wet weight of the paint composition.
- the solvent for dispersing the NAD resin that will be a binder various organic solvents that are commonly used for paints can be used without any particular restrictions.
- solvents in which the components of the NAD paint composition are dissolved or dispersed are alcohols such as methanol, ethanol, propanol, isopropanol, butanol, isobutanol and benzyl alcohol; alcohol/water mixtures such as ethanol/water mixtures; aliphatic, cycloaliphatic and aromatic hydrocarbons such as white spirit, cyclohexane, toluene, xylene and naphtha solvent; ketones such as methyl ethyl ketone, acetone, methyl isobutyl ketone, methyl isoamyl ketone, diacetone alcohol and cyclohexanone; ether alcohols such as 2-butoxyethanol, propylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethyl ether and butyl diglycol; esters such as ethyl acetate, propyl acetate, methoxypropyl acetate,
- Useful solvents are in particular hydrocarbon type solvents and include aliphatic, alicyclic and aromatic solvents. In the present invention, it is preferred to employ an aliphatic hydrocarbon solvent and/or an alicyclic hydrocarbon solvent, or such a solvent in the major amount.
- Suitable aliphatic and alicyclic hydrocarbon solvents include, for example, n-hexane, iso- hexane, n-heptane, n-octane, iso-octane, n-decane, n-dodecane, cyclohexane, methyl- cyclohexane and cycloheptane.
- aromatic solvents include, for example, benzene, toluene, xylene and decalin.
- Commercial products include, for example, SOLVESSO 100 and SOLVESSO 150 (manufactured by Exxon Chemical Co.); and SWAZOLE (manufactured by Maruzen Oil Co., Ltd.).
- the paint composition of the invention further comprises rosin wherein at the most at the most 90% by weight of the rosin has conjugated, non-aromatic double bonds.
- rosin having "conjugated, non-aromatic double bonds" will have a certain impact on the overall mechanical properties of the paint composition.
- at the most 90% by weight of the rosin should have conjugated non- aromatic double bonds.
- even lower contents e.g. at the most 50% by weight, such as at the most 40% by weight, of the rosin may advantageously have conjugated, non-aromatic double bonds as such types of rosin are believed to provide better mechanical properties.
- rosin, resinates and the like is intended to refer to gum rosin; wood rosin of grades B, C, D, E, F, FF, G, H, I, J, K, L, M, N, W-G, W-W (as defined by the ASTM D509 standard); virgin rosin; hard rosin; yellow dip rosin; NF wood rosin; tall oil rosin; or colophony or colophonium.
- the terms rosin resinates and the like are also intended to include suitable types of modified rosin, in particular oligome ⁇ sation; hydrogenation; dehydrogenation-hydrogenation/disproportionation/dismutation; etc., that will reduce the amount of conjugated non-aromatic double bonds.
- At least 25% of said rosin should be in the form of a metal resinate.
- at least 40%, such as at least 50%, e.g. at least 60%, in particular at least 75%, or event at least 90%, or more, of the rosin is in the form of a metal resinate.
- said metal resinate advantageously constitutes in the range of 1-40%, or 1-30%, or 1-15%, e.g. 2-13%, such as 2.5-10%, by wet weight of the composition.
- metal resinates can either be obtained commercially or may be prepared prior to mixing with the other paint constituents.
- the metal resinates may also be the result of a reaction between rosin components and metal constituents of a paint. However, in this instance it is important to ensure that reaction between e.g. metal oxides and the rosin has proceeded to the desired level.
- Determination of the content of conjugated, non-aromatic double bonds may be performed by using ultraviolet spectroscopy (UV) techniques or infrared spectroscopy (IR) (preferably Fourier transformation IR) techniques as realised by the person skilled in the art, e.g. as described in Naval Stores (Stump, J.H. ed.), Chapter 25: Quality Control (Tall oil, rosin and fatty acids), page 860, and ASTM Designation D 1358-86.
